For DC Current signal (Figure 10)
Step 1:
Connect the black test lead cable for measurement to the “COM” input terminal and the red test lead cable to the
“mA” input terminal.
Step 2:
Connect the other end of the cable to the measuring terminals of the equipment under test while making sure the
polarities are correct.

Warning
z
Before connecting the calibrator to the device under test, switch OFF the power to the device.
z
Do not apply voltage or current exceeding the allowable voltage (60 V peak) or current (55 mA). Exceeding the limits will
endanger the instrument and create a risk of personal injury due to electrical shock.
z
Mistaking the voltage input terminal for the mA current input terminal, and vice versa, when wiring, is extremely
dangerous. Take great care in making connections; always check the accuracy of the connection configuration.
z
The current input terminals are equipped with a built-in current input protection fuse. Over-current input to the terminals
will cause the fuse to blow. If the fuse is blown, replace it with one with the specified ratings. For details on fuse
replacement, see the “Replacing the battery and fuse” section.
Warning
Wiring or operational errors can lead to damage to the instrument and personal injury due to electrical shock. Exercise the
utmost care when carrying out the measurement tasks.
6.2 Measuring DC Voltage
Step 1:
Ensure that the test lead cables are not connected to the instrument or device under test.
Step 2:
Using the function key
(V),
select DC Voltage measurement function.
Step 3:
Connect the test lead cables to the terminals of the instrument under test.
Step 4:
Using the
(RANGE)
key, select a desired range from 200mV, 5V, 50V. The selected function, the measured value,
and the unit of measure are shown in the upper area of the LCD.
